Currently, I have 2 females of the same litter with one male of a different litter. And in a 20 gallon aquarium tank, I have one female, and a male both from different litters.
Could I take one male and a female from one tank, and swap them round with the other two. So they are on Their own, and when the female is in oestrus it puts more emphasis onto her, so the male has only her, without getting spoilt for choice.
Mice are indiscriminate breeders. It will not increase nor decrease the breeding.
